We propose a nonparametric framework for the analysis of networks, based on a natural limit object termed a graphon. We prove consistency of graphon estimation under general conditions, giving rates which include the important practical setting of sparse networks. Our results cover dense and sparse stochastic blockmodels with a growing number of classes, under model misspecification. We use profile likelihood methods, and connect our results to approximation theory, nonparametric function estimation, and the theory of graph limits.

Distance-Preserving Embeddings in Inhomogeneous Random Graphs
On supercritical inhomogeneous random graphs, multi-scale landmark embeddings achieve (1±ε)-distortion of shortest paths at dimension Ω(n^{1-ε} log n), far below worst-case, with universal kernel extensions and transf...

Bias-Corrected Multiplier Bootstrap Inference for Spectral Edges of Large Covariance Matrices
A calibrated multiplier bootstrap regularizes bulk-edge eigenvalues to a Gaussian scale, bias-corrects the induced edge shift, and produces valid edge CIs plus a spike-count estimator.

Decorated graphons for temporal network estimation
Dynamic networks can be modeled as decorated graphons whose edge labels are binary time-series laws, estimated by two-stage blockwise least squares with rates depending on the number of time steps and edge-estimator quality.

A Spectral Framework for Graph Neural Operators: Convergence Guarantees and Tradeoffs
Three existing graphon sampling bounds give GNN eigenvalue-convergence rates of (log n)^-1/4, sqrt(log n/n), and (log n/n)^1/4; the note unifies and tests them, finding all loose.
